The purpose of the present invention is to ensure a stable operating state of a speaker device by increasing the rigidity of the entire frame by ensuring especially high rigidity of a portion on the side on which a magnetic circuit is attached. A speaker device is provided with: a diaphragm that is vibrated when sound is outputted; a magnetic circuit having a magnet and a yoke; and a frame having an outer annular part to which the edge of the diaphragm is attached and an inner annular part to which the magnetic circuit is attached. At least one leg part connecting the outer annular part and the inner annular part is provided in the frame, the leg part comprises an outer end section continuous with the outer annular part, an inner end section continuous with the inner annular part, and a narrow section located between the outer end section and the inner end section and having a narrower width than the outer end section and the inner end section, in the narrow section, a narrowest section having the narrowest width is provided in an intermediate portion between the outer end section and the inner end section, the narrowest section is located closer to the outer annular part side than the center of the outer annular part and the inner annular part, and both side edges in the width direction including the narrowest section in the narrow section are formed in a curved shape or a linear shape. |
